It seems to me that the report is intimating that this was a bleeds off takeoff, why else post the Irish reports which were also bleeds off. There were other reports they could have included where a defective outflow valve was the culprit, but they didn't. After-crash photos of the control panels also seem to support that theory.
It seems quite plausible (though not proven) that the pilots were in the process of reconfiguring from bleeds off when the E&E recurring problem popped up, diverting the pilot's attention.
Some posters contend that a bleeds off was not done, as conditions did not warrant it. However, 115 pax going away on holiday will be carrying a lot of luggage, thereby adding a lot of weight. And, in mid-August on Cyprus, the temperatures were probably in the 30s (celsius), even in the morning.
